The Grassy Knoll (Dallas, TX)
Dealey Plaza and its "grassy knoll" are located in downtown Dallas. Besides being a pretty park, it is the site of the assassination of President Kennedy. Supposed shooter Lee Harvey Oswald was perched inside the Texas School Book Depository, but many believe a second shooter hiding on the hillside fired the shot that killed JFK. In the moments following the shooting, police rushed to the site and nearly 100 eyewitnesses testified that they heard shots coming from Dealey Plaza. The Warren Commission discredited the grassy knoll theories to solidify the "lone gunman" story.
